WATER-GAGE.

Specification of Letters Patent.

Patented July 26, 1910.

Application filed December 14, 1909. Serial No. 533,066.

To all whom it may concern:

Be it known that I, WILLIAM KYLE An- NOLD, a citizen of the UnitedStates, resident of Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented a new and useful Improvement inWVater-Gages; and I do hereby declare the following to be a full, clear,and exact description thereof.

My invention relates to an improvement in a driptwater-gage for testingthe-height of water in boilers.

The object of my invention is to produce a water-gage the constructionof which will preclude the lodgment of scale or other extraneous matterbetween the parts and the consequent interference and impairing of thesame thereby.

In the accompanying drawings, Figure 1 is an elevation partly insection, showing my invention connected to a broken section of a boiler.Fig. 2 is a plan View on line II-II I f Fig. 1 showing an opening in thehead of the gage out of alinement with a discharge outlet of the gage.

The reference numerals in the following specification refer to likeparts in the drawings, in which, referring to Fig. 1, a nipple 10 isconnected at the end 10 thereof to the boiler 11, and to the other endof said nipple is secured a T -joint 12. To the lower threaded end 12 ofthe T-joint a plug 13 is threadedly connected, which is provided with anopening 14. A suitable head 15, having an opening 15 therein, is adaptedto seat upon the inner face of the plug and is suitably secured to oneend 16 of the stem 16 around which and carried upon the upper end 15 ofthe head 15 a coil spring 17 is arranged, the latter having a loosewasher 18 on its upper extremity. A bonnet 19 is threadedly connected tothe upper end 12 of the T-j oint, the end 19 of the bonnet acting uponthe washer 18 to compress the spring 17 against the head 15 and impart aflexible bearing to the latter against the plug 13. A stuffing-box 20'is threadedly secured to the outer end of the bonnet and a small handwheel 21 is suitably attached to the top of the stem.

With the parts constructed and arranged as shown, and the openings 14,15 out of alinement, as shown in Fig. 11, the operation of my inventionis as follows: By means of the hand wheel 21 the stem 16 is operated torevolve the head 15 until the opening 15 registers with the openings 14in the plug when, if the height of water in the boiler 11 is above thelower inner level of the nipple, the fact will be indicated by itspassing through the apertures 14, 15, no show of water while theopenings are in alinement indicating that the water in the boiler isbelow the nipple, when the head may again be revolved to change theposition of the opening 15 relative to the opening 14.

It will be apparent that in operating the head 15, its position relativeto the plug is not changed and that a perfect closure of those parts maytherefore be maintained to exclude the water from between the parts andto prevent scale, grit or other matter from being lodged between theparts and impairing the parts and the closure. And further, that theradial position of the opening 15' on the head 15 permitting it to berevolved by the stem out of alinement with the opening 14 peculiarlybreaks the lines of communication between the water and the opening soas to effectively prevent a gradual leakage of the water through thejoints.

It will be understood that more than one gage may be used on a boiler,if desired, for the purpose of testing different intervening heights ofthe water in the boiler. And it will be apparent that a sliding memberWithout a communicating opening may be used in connection with the part14, if desired, instead of the part 15, and that various changes in theconstruction and operation of the parts may be made without de partingfrom the spirit of my invention.

What I claim as my invention and desire to secure by Letters Patentis- 1. A water gage, comprising a nipple, a T-shaped member connected tosaid nipple, a detachable valve seat having a discharge outlet andcarried on one arm of the T- shaped member, a valve stem operatively 100projecting from the opposite arm of the T- shaped member, a valve havlnga perforation therein carried by the valve stem and fitted against thesaid valve seat.

2. A water gage, comprising a nipple, a 105 stem in the opposite arm ofthe T-shaped 110 member, a valve having a perforation there- Intestimony whereof, I the said WILLIAM in gecflilreii1 t0 the innelll'end 1of the valve stem K. ARNOLD have hereunto set my hand.

an tte against t e Va ve seat, a loose Washer carried upon the valvestem at the WILLIAM KYLE ARNOLD 5 base of the bonnet, a spring on thesaid stem Witnesses:

between the Valve and the Washer, and means J OE M. CLARK,

for operating the valve stem. CHAS. RAWSON.
